Ubuntu 20.04 smb

SMB (Server Message Block) is a protocol used for sharing files, printers, and other resources between computers on a network. Here are the steps to set up SMB on Ubuntu 20.04:

1. Install Samba:

sudo apt update
sudo apt install samba

2. Create a directory to share:

sudo mkdir /home/<your-username>/smb_share

3. Edit the Samba configuration file:

sudo nano /etc/samba/smb.conf

4. Add the following lines to the end of the file:

[smb_share]
    path = /home/<your-username>/smb_share
    read only = no
    guest ok = yes

Replace `<your-username>` with your actual username.

5. Save and exit the file.

6. Restart the Samba service:

sudo service smbd restart

7. Open the file manager and navigate to `smb://localhost/smb_share` to access the shared directory.

Note: If you want to share the directory with other computers on the network, you may need to configure the firewall and Samba user accounts accordingly.
